Hotel/Hospitality Mode: Hospitality mode on or off makes no difference Details below:Ĭonnectivity: 9600 baud, 8 bit, no parity, 1 stop bit, no hardware flow control I'd love some help figuring out what I'm doing wrong. I can turn it on, but no other command is responsive. Like lucastx, I'm having a terrible time trying to control the TV via Ex-Link. I have a 2017 Samsung QLED TV (QN75Q70RAF).
